For those of you still looking for the perfect Father's Day or graduation gift, your prayers have been answered. Amazon.co.uk has wisely decided to offer my book in a special deal along with Lisa Randall's new book, Warped Passages (as noticed by Lubos).

To be honest, one book doesn't lead naturally into the other; Lisa's is a popular-level exposition of branes and extra dimensions, while mine is a graduate-level text in general relativity. But hey, you could do worse.

What I want to know is: who are John Neely and Richard Kibbe, and why does amazon.co.uk think they are co-authors of my book? I'm pretty sure I've never heard of these guys. Hope they're not cutting in on my substantial royalties.
